【摘要】 通过对云南4个水位观测点模拟与数字化并行观测资料的对比分析,认为同一个观测点的模拟与数字化观测数据内在质量接近、数据相关性好、数据的变化形态及地震同震响应特征相似,在这些并行观测的观测点上数字化观测可以取代模拟观测。更多还原

【Abstract】 By a comparative analysis of the data of underground water level simultaneously observed by analog seismometer and the digital one at four stations in Yunnan,we find that the two kinds of data have the following relations: close inherent quality,high correlativity,the same time-variation shape,and the similar co-seismic response.In view of its advantages of small disturbance,timely information and easy maintenance,we conclude that the digital observation can replace the analog one.更多还原
